Tan 60° = AD/BD = √3 / 1 = √3. We can also write the value of cos 60 degrees in decimal form as: cos 60° = 1/2 = 0.5. Also, we can write the values of sine, cosine and tangent with respect to all the degrees in a table. Let us draw a table with respect to degrees and radians for sine, cosine and tangent functions.

Cos 30° = √3/2 is an irrational number and equals to 0.8660254037 (decimal form). Therefore, the exact value of cos 30 degrees is written as 0.8660 approx. √3/2 is the value of Cos 30° which is a trigonometric ratio or trigonometric function of a particular angle. Cos 30. Another alternative form of Cos 30° is pi/6 or π/6 or Cos 33 (⅓) g . 1045
